.To all wh'om it may concern."

Be it known that I, LEWIS GUILD, of Dedham, in the county of Norfolk andState of Massachusetts, have invented certainl Improvements in Rolls forClothes Wringing and Washing Machines, of which the following is a full,clear, and exact description, reference being had to the accompanyingdrawings, making part of this specification, in which- Figure l 'is aperspective view of a roll foraclothes-wringing machine without itscovering of india-rubber. Fig. 2 isa longitudinal Section through thesame. v

lfu rolls for clothes wringing and washing machines, where an iron shaftpasses lengthwise through the rollto give it strengthand to fornijournals on which the roll turns, theiron is liable to be rusted by thewater cominginto contact with it and to stain the clothes; also, where awooden roll is placed upon the iron shaft to be afterward covered withindiarub-v which serve to secure the wooden roll to the,

Shaft and to protect the ends of the'india-rubber covering, which isafterward appliedto the roll.

I am aware thatir'on shafts have beenwashed or coated with tin, zinc,and alloys of metals to protect them from rust; but this washingorgalvaniz'ingof Athe shaft would not accomplish the end I have VYinv-iew,which is not only to protect the shaft,but also to secure the woodenroll to the shaft and provide the collars which arenecessary to protectthe rubber covering of the roll.

The copper moldy is heated' to preventthe chilling of the casting.
